The Rupee opened weak on Wednesday, with risk aversion triggered by the Greenland dispute compounding persistent pressures and leaving the currency reliant on the central bank's support.Unnerved by U.S. President Donald Trump's threats over Greenland and the potential for a U.S.–Europe trade dispute linked to the issue, investors swung into risk-off mode, dumped the dollar, and bought into safe-haven assets. Asian currencies were caught between a softer risk appetite and a weaker dollar, leaving them mixed with limited follow-through. While in Asia terms, the rupee should be "good", "the thing is it's already under pressure so this kind of risk-off just hits it harder than the rest", a currency trader at a bank said.The rupee on Tuesday came within a whisker of its lifetime low, slipping to 91.0525, with bankers saying the Reserve Bank of India was present to support the currency for most of the session. Further denting risk sentiment was a sell-off in Japanese bonds, which pushed yields to record highs on fiscal concerns.The move is vying for market attention with the Greenland dispute, and investors focus on Wednesday will by on Trump’s interview at the at Davos.
